C) Urine becomes more diluted.
D) The frequency of voiding increases.
Ans: B

When antidiuretic hormone is present, the distal tubule of the nephron becomes more permeable to water. This causes the renal system to retain more water. A lack of antidiuretic hormone causes increased production of dilute urine. Antidiuretic hormone does not cause thirst.
